Definitions

  • the present invention relates to a process for steel treatment and a steel treatment plant.
  • pickling lines in steelmaking are combined with annealing lines, with the corresponding stainless steel hot strip or cold strip usually passing through the annealing furnace first and then pickled.
  • catalysts which have operating temperatures between 200 ° C and 300 ° C.
  • SCR Select Catalytic Reduction
  • these catalysts are also known for the treatment of nitrogen oxide-containing exhaust gases from chemical metal treatment, especially in pickling processes.
  • the energy input in the combined annealing pickling lines is still very high. Accordingly, it is an object of the present invention to further reduce the use of energy in the operation of a pickling plant.
  • the process exhaust air from the steel pickle is heated to catalyst operating temperature and fed to a catalyst for reducing the nitrogen oxide concentration.
  • the process exhaust air conducted through the catalyst is supplied to at least one heating burner of the annealing furnace as combustion air.
  • the thermal energy which was supplied to the process exhaust air to the pickling plant, in order to allow the catalytic decomposition or catalytic purification of the process exhaust air in the catalyst, in turn as heating energy for the annealing furnace be used.
  • the amount of energy used to operate the annealing furnace can be reduced by the amount of heat re-introduced via the cleaned process exhaust air.
  • the process exhaust air is released into the environment after purification by the catalyst. The resulting energy loss can be reduced by means of the specified method, since the waste heat from the catalyst can also be used to heat the annealing furnace.
  • the process exhaust air of the steel pickle is heated upstream of the catalyst by means of an auxiliary burner.
  • the heating of the process exhaust gas can preferably be carried out by means of a heat exchanger which uses the waste heat of the furnace air from the annealing furnace for heating the process exhaust gas.
  • the process exhaust air of the steel pickling is preferably washed in an acid scrubber before it enters the catalyst.
  • At least part of the process exhaust air is added after passing through the catalyst of the process exhaust before the catalyst, preferably via an overhead line.
  • a dilution of the HF concentration can be achieved and, on the other hand, additional heat energy can be supplied.
  • condensation of the hydrofluoric acid is prevented and, on the other hand, heating of the process waste gas / furnace exhaust gas mixture to a temperature which is necessary for the catalyst can be achieved.
  • the process exhaust air heated after the catalyst can also be added to a part of the process exhaust air upstream of the catalyst so as to also achieve a heating of the process exhaust air which comes from the HF scrubber and at the same time permit a dilution, which is a condensation of the hydrofluoric acid counteracts.
  • the kiln exhaust gas of the annealing furnace may preferably be used to heat, for example via a heat exchanger, the fresh kiln feed which is supplied to the heating burners of the annealing furnace. Also in this way an improved energy flow is achieved within the system.
  • the furnace exhaust gas from the annealing furnace can also be used to generate process steam.
  • the steel treatment plant has an annealing furnace for annealing steel, a steel pickling for pickling the steel, and a catalyst for reducing the nitrogen oxide concentration of the process exhaust air from the steel pickle.
  • a heating device for heating the process exhaust air in front of the catalyst is provided in order to heat the process exhaust air to catalyst operating temperature.
  • a supply device for supplying the process exhaust air guided through the catalyst to at least one heating burner of the annealing furnace is provided.
  • the process exhaust air after it has passed through the catalyst, contribute to the heating of the annealing furnace.
  • the process exhaust air was added to the catalyst upstream of the catalyst to heat it to catalyst operating temperature. This heat can not be lost by the proposed system, but can be used to heat the annealing furnace. In this way, the overall energy balance of the steel treatment plant can be improved.
  • FIG. 1 shows a steel treatment plant 1 with an annealing furnace 2 for annealing steel and a Stahlbeize 3.
  • the steel treatment plant 1 is used, for example, to anneal steel and pickling, for example, in cold or hot strip to achieve a favorable surface structure of the product.
  • the steel strip 10 which is supplied for example as a coil 12, first unwound and then annealed in an annealing furnace 2.
  • the steel strip 10 is then passed into a steel pickling 3 in which it is subjected to an acid treatment, for example to remove scales from the surface and to obtain a high-quality surface structure.
  • an acid treatment for example to remove scales from the surface and to obtain a high-quality surface structure.
  • hydrofluoric acid ie hydrogen fluoride (HF)
  • HF hydrogen fluoride
  • the annealing furnace 2 is typically heated with heating torches 20 to the appropriate annealing temperature.
  • the Aufmorenner are preferably burner, which have a low nitrogen oxide output. Such burners are also referred to as low NOx burners.
  • the furnace exhaust gas produced by the Aufmorennern 20 is discharged via an exhaust discharge 22 from the annealing furnace 2.
  • the furnace exhaust gas still has a high temperature, for example in the range of 300-600 ° C.
  • the introduction of the still hot steel strip 10 into the liquid acid also produces process exhaust air which is discharged from the steel pickling 3 via corresponding exhaust air vent 30.
  • the process exhaust air typically comprises nitrogen oxides (NOx) and acid radicals, for example radicals of hydrofluoric acid (HF). These hydrofluoric acid residues are removed as far as possible from the process exhaust air 30 in an acid scrubber 4.
  • the process exhaust air still has temperatures of about 40 ° C after the acid scrubber 4.
  • a catalyst 5 is provided through which the process exhaust air is passed.
  • the catalyst 5 may be, for example, an SCR catalyst (Selective Catalytic Reduction Catalyst).
  • SCR catalyst Selective Catalytic Reduction Catalyst
  • the catalyst typically requires higher temperatures in order to be able to carry out the splitting of the nitrogen oxides than the temperature which the process gas has after the acid scrubber 4. Accordingly, the process gas must be heated from about 40 ° C to the temperature required by the catalyst, which is in the range of 140 ° C to 400 ° C. This heating can take place either via a heat exchanger 6, in which the process exhaust air from the steel pickle 3 is heated after the acid scrubber 4.
  • the heat exchanger 6 may preferably use the heat energy from the furnace exhaust gas, which is supplied via the exhaust gas guide 22 to the heat exchanger 6, for heating.
  • auxiliary burner 60 are provided, which can also serve to heat the process exhaust gas from the steel pickling 3 after the acid scrubber 4.
  • the furnace exhaust gas 22 can also be used to heat the fresh air, which is the Aufmorennern 20 supplied.
  • the fresh air is supplied via a fresh air supply line 70 to the Aufmorennern 20 of the annealing furnace 2, wherein the fresh air is also heated by the furnace exhaust / air heat exchanger 7.
  • the heating torches 20 of the annealing furnace 2 a significantly heated burner air is supplied, wherein the supplied burner air temperatures of already 100-500 ° C may have. Accordingly, the energy necessary for heating the annealing furnace 2 can be reduced because the amount of heat, which originates on the one hand from the steel pickle 3 and on the other hand is supplied to the fresh air via the furnace exhaust gas, is also used to heat the annealing furnace 2.
  • the oxygen content of the process exhaust air corresponds approximately to the oxygen content of the normal combustion air in the heating burners 20, since no combustion occurs in the steel pickling. Accordingly, the process exhaust air from the Stahlbeize 3 still carries the air oxygen content and can be supplied to the Auffilbrennern 20 directly as burner air. The amount of heat present in the process exhaust air can be used correspondingly directly for heating the annealing furnace 3.
  • the furnace exhaust gas is finally discharged through the chimney 8 to the environment.
  • the furnace exhaust gas 22 contains not only the actual furnace exhaust gas, which was discharged from the Heilbrennern 20, but also the process exhaust air from the Stahlbeize 3 after it has passed through the Aufmorenner 20.
  • the furnace exhaust gas is additionally used for generating process steam by means of a heat recovery steam generator 9, which is inserted into the exhaust pipe 22.
  • a heat recovery steam generator 9 which is inserted into the exhaust pipe 22.
  • the method of the present invention makes it possible to further reduce the primary energy input in the steel treatment by reusing the respective amounts of energy contained in the respective exhaust gases as much as possible.
  • the nitrogen oxide-containing and hydrofluoric acid-containing process exhaust air of the steel pickle 3 is passed through an acid scrubber 4 in the form of the HF scrubber to reduce the hydrofluoric acid concentration.
  • preheated and cleaned process exhaust air is supplied after passing through the catalyst 5 by means of the addition line 34 in order to achieve a heating of the process exhaust air, to dilute it and to avoid the HF condensation.
  • the process exhaust air is heated to operating temperature of the catalyst 5, either by means of a heat exchanger 6, which uses the heat energy of the furnace exhaust gas from the annealing furnace 2, or by means of an auxiliary burner 60th
  • the nitrogen oxides are split and deposited accordingly.
  • the then removed from HF and nitrogen oxide process exhaust air is added to the Aufmorennern 20 as combustion air via the overhead line 32. Accordingly, the amount of heat that is present in the process exhaust air after passing through the catalyst 5, can support the heating process of the Aufmorenner 20 in the annealing furnace.
  • the kiln exhaust gas from the annealing furnace 2 is used to preheat the combustion air, which is supplied to the Aufmorebrennern 20 via an overhead line 70, by means of a furnace exhaust gas / air heat exchanger 7.
  • the further furnace exhaust gas stream can also be used to produce process steam in a corresponding steam generator 9.
  • the amount of heat in the furnace exhaust gas is then further used in a heat exchanger 6, in turn, to heat the process exhaust air from the Stahlbeize 3 to the catalyst operating temperature.
  • the furnace exhaust gas is then discharged through the chimney 8 to the environment. The amount of heat has been removed from the furnace exhaust gas as much as possible and kept in the steelmaking or steel treatment system.
